Design Guideline of Single-Stage Flyback AC-DC Converter Using FAN7530 for LED Lighting
This application note describes the single-stage power factor correction (PFC) and presents the design guidelines of a 75W universal-input, single-stage PFC for LED lighting applications. Flyback converter topology controlled by the critical conduction mode control IC, FAN7530 is applied and several functions; such as CV/CC mode feedback circuits, cycle-by-cycle current limit, soft-starting fun...
متن کاملA New Single-Phase Single-Stage AC-DC Stacked Flyback Converter With Active Clamp ZVS
Single-stage AC-DC converters integrate an AC-DC front-end converter with a DC-DC backend converter. Compared with conventional two-stage AC-DC converters, single-stage ACDC converters use less components and only one controller, which is used to regulate the output voltage. As a result, the cost, size and complexity of AC-DC converters can be reduced, but single-stage converters do not perform...
متن کاملNCL30001 - High-Efficiency Single Stage Pwr Factor Correction & Step-Down Offline LED Drvr
The NCL30001 is a highly integrated controller for implementing power factor correction (PFC) and isolated step down ac−dc power conversion in a single stage, resulting in a lower cost and reduced part count solution. This controller is ideal for LED Driver power supplies with power requirements between 40 W and 150 W. The single stage is based on the flyback converter and it is designed to ope...
متن کاملDynamics Analysis of Lfr Model for a Single-stage High Power Factor Correction Diagonal Half-bridge Flyback Ac/dc Converter
By means of a graft scheme, a buck-boost cell and a wide range diagonal halfbridge flyback cell are combined to create a novel single-stage high power factor correction (HPFC) diagonal half-bridge flyback ac/dc converter in this paper. When both of the two cells operate in discontinuous conduction mode, the proposed converter exhibits high power factor and low bulk capacitor voltage stress inde...
متن کاملA Novel Single-stage AC/DC Converter with ZVS Characteristic
A novel single-stage AC/DC converter is proposed in this letter. The converter is designed by integrating a sepic circuit and a flyback circuit, the circuit work in the quasi-resonance state, and the switch is turned on in the zero voltage switching (ZVS) state, which decreased the switching losses of the converter Streszczenie. Opisano nowy konwerter AC/DC. Układ pracuje w stanie quasi-rezonan...
